Specification of Letters Patent.

Patented July 23, 1918.

Application filed July 19, 1917. Serial No. 181,650.

To'all whom it may concern:

Be it known that I, Fnnonron E. SCHNEI- DER, a citizen of the United States, residing at Highland, in the county of Iowa and State of Wisconsin, have invented certain new and useful Improvements in \Vire- Stretchers; and I do hereby declare the following to be a full, clear, and exact descrip tion' of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in wire stretchers.

The object of this invention is to provide a wire stretcher capable of being adjusted to a fencing wire so that an even pull may be distributed thereon prior to the stapling of the ends to posts. A

A still further object of this invention is to provide a wire stretcher, which will be simple, practical and comparatively inexpensive in construction and one that can be manufactured and sold at a low cost.

With these and other objects in view the invention consists in the novel combination and arrangement of parts hereinafter more fully described and set forth in the claims hereto appended.

In the drawing Figure 1 is a side elevation illustrating my improved wire stretcher as applied and in use,

Fig. 2 is a fragmentary side elevation illustrating the clamping plates and cam levers,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2,

Fig. 4.- is a sectional view taken on the line 4 -4: of Fig; 2, and

Fig. 5 is a perspective view of one adjusting block and clamping plate and cam lever.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

Referring to the drawing, the numeral 1 designates a substantially rectangular supporting member, provided with a spaced ries of longitudinally extending slots 2. An adjusting block 3 is slidably arranged in each ofthe slots 2 as illustrated. The blocks 3 are held against movement from its respective slot 2 in one direction by a rectangular strip 4. The strips 4 are secured to one face of each block intermediate the ends thereof as at 5, and these strips are arranged tran q versely with relation to the supporting memher 1 thus constituting a bearing as it has a sliding engagement with one face of the su 'iporting member 1 and. this permits the adjusting block 3 to move freely in its respective slot.

A clamping plate 5' is rigidly secured to the other face of each block adjacent the upper end thereof as at 6 and these plates are arranged transversely with relation to the supporting member and at right angles to the slots. The clamping plates 5' cooperate with the strips i and retain the blocks in the slots and also permit free sliding movement thereof. The under side of each clamping plate is serrated or roughened as at 7 to constitute a gripping jaw.

A cam lever 8 is pivotally secured as at 9 to each adjusting block 3 and have their peripheral. edges in close proximity to the under roughened side of each of the clamping plates 5' to permit a fencing wire to be gripped tightly thcrebctween so as to permit the fencing wire to be evenly stretched I\Ovhen pull is applied to the supporting mem- Each'of the cam levers 8 has a laterally extending reduced. portion 9 formed in tegrally therewith which constitutes a handle and permits the cam levers to be rotated so that the ends of. a fencing wire may be readily placed between the peripheral faces of the cam levers and the under roughened side of each of the clamping plates 5.

The supporting member 1 is provided on one longitudinal side and adjacent each end thereof with an eye 10 to which are secured the ends of the flexible chain 11 as at 12. The chain 11 has secured to its medial portion a connecting ring 13 to which is detachably secured the power applying or pulling mechanism, designated in its entirety by the numeral 14.

It can be readily seen that by the connection of the flexible chain to one longitudinal side edge of the supporting member 1, that when the fencing wire designated A in the drawing is arranged between the respective cam and clamping plates, an even pull will be distributed to the wire, permitting the wire to be easily and quickly stretched and stapled to its respective post designated B in the drawing.

The pulling mechanism used in connection with this s pporting m er s unseat of the cable. 19..

as being applied to an anchor post designated C having secured thereon adjacent its upper end a flexible connection 15 in which is secured the hook 16 carried by the sheave 17. An eye 18 is secured to the sheave 17 and has connected thereto one end The cable 19 .is .passed through the sheave 20 Which in turn is connected as at 21 to the connecting ring 13' of the Wire stretcher as illustrated. The cable isthen fextended around the sheave '17 and has connected'to its ends any suitable type of means "for pulling the cable to permit "the Wire stretcher l to be lpulledin the directio'n'of the anchoring post thu's effecbetween the peripheral surface of each clamping lever 8 and its respectiveclamping plate '5. The lever '8 is then .moved by grasping thehandle and urging the same downwardly 'b1 ndi 'ng the fencing Wires between the roughened underside of the clamping "plate 5 and cam surface of the levers "8. In this Way the fencing Wires are firmly heldto the supporting member land the pullin mechanism is ;put in. operation,

thereby e ectively stretching the fencing Wires as will be obvious from the disclosure.

What is;cla'imed 1, A 'vvire stretcher comprising "a rectangular supporting member provided with a series of spaced longitudinally extending slots, an adjusting block slidably arranged in each slot, a retainin strip secured to one faceflo'f' each block and. at right angles to the slot thereof, a clamping plate secured :to the other face of each of the blocks and havin its underside rou hened and a cam lever pivotallys'ecured to each of the adgu'lar supporting member provided with i a spaced series of longitudinally extending slots,an adjusting blockfarrange d vertically in'each slot, a strip secured transversely to one face of each block and having an abutting engagement with one face of theflsupporting nember'to retain the blocks in their respective slots and against movement gin one direction, clamping plates'secured :to the other face of each block and preventing movement of the adjusting "blocks in the other direction, a cam lever pivotally securedflto one face of each block and located in close proximityto' the under side of the clamping plates, said slots peri'iiitting of the vertical adjustment of the "blocks'to ,ac-

commodate fencing Wires, and a power ap-- plying mechanism adapted to be secured to the supporting member, as and for the purpose specified, V p In testimony WhereofI affix my signature in presence of two Witnesses.
